T0 @ZZ whom t may concern:

Be it known that we, SACKvILLE G. LEY- SON and HOWELL THOMAS, of Rome, in the county of Oneida and State of New York, have invented a new and useful VImprovement in Machines for Manufacturing Brick, which improvement is fully set forth in the following specification and shown in the accompanying drawings. I l

The object of our invention is to produce a rapid -Working brick machine, the machine being intended to make bricks of true prismatic form having sharp and well-defined corners and edges, like the pressed brick used in the better class of brick buildings.

Referring to the drawings, Figure l is a plan of our improved brick-machine, parts being shown in two positions by full and dotted lines; Fig. 2, a similar view of the machine sectioned horizontally, as on the `dotted Aline fr in Fig. 3, parts being broken away and omitted; Fig. 3, a side elevation of the machine, seen as indicated by arrow y in Fig. l Fig. 4, an elevation of the device, seen as indicated by arrow .z in Fig. l; Fig. 5, a side elevation, seen as `indicated by arrow in Fig. l, parts being broken away and omitted, parts of the base-block and mold-cylinder being vertically sectioned, as on the dotted line y in Fig. l; Fig. 6, a vertical section through the axis of the mold-cylinder, taken as on the dotted line c e in Fig. 1, the View being in the direction in which Fig. 4 is seen; Fig. 7, a vertical central sectionl through one of the plungers to show the stops therefor; Fig. 8, Sheet l, a view of the under side of a part of the feeder; Fig. 9, Sheet 3, a cross-section of one of the blades of the feeders, taken on the dotted line @c2 in Fig. 3; and Figs. 10 and 1l, Sheet 2, show, respectively, a side elevation and plan of the lifting-bar for the rams provided with stiffening-springs. Figs. 6 to 9, inclusive, are drawn to a scale twice the size of that of the other figures.

Referring to the parts shown in the drawings,` A is a circular hopper for receiving the brick-clay, containing rotary mixing knives or grinders B for t-he clay. l y v O is a receiving-pan containing a rotary feeder D for the molds.

E is a mold-cylinder containing mold-,cavities or molds, resting upon friction-rolls a, and

tted to turn upon a central spindleb. l

d is a main driving-shaft for the machine,

with drive-pulleys e, drive-belt f, and inertiag isa vertical shaft carrying the grinders or knives B, provided with a bevel-gear h;

t' is a shaft for driving g, provided with a i bevel-pinion k for the wheel h, and geared to the main driving-shaft by spur-gears Z and n. o is a vertical shaft carrying the feeder D,

Vdriven by means of a cross belt or c hain p on pulleys r and s, secured to the respective shafts g and o.

is a vertical shaft carrying a segmental gear u for driving themold-cylinder, the latter being provided with gear-teeth fu, with 1 which the segmental gear engages. l w isa miter-gear rigid with t. c is a horizontal shaft to drive t, being provided with a miter-gear b to engage w. a

is driven by the main shaft d by means of E c is a circular inclined track constituting an elevator for the rams, it being concentric with the spindle h, up along which the rams move as the mold-cylinder carries them around. The segmental gear it, as shown, has just one-fourth as many teeth as the cylinder E, so that each action of the gear `upon the cylinder turns the latter through just onefourth of a complete revolution. v

The shaft a is provided with a crank f', and g is a bar or lever held at h to move vertically and to be operated by the crank.' This lever is in such position that when the cylinder stops after each movement one of the rams will stand directly over it, as appears in Figs. 4, 5, and G. The lever may be provided with springs u2, as shown in Figs. 'l0 and ll, if found necessary, and it, with the crank, constitutes a driver for the rams as the latter are presented to it by the successive movements of the mold-cylinder. shaft a turns constantly while the machine is running, andwhile a ram is Over the lever the rain with great force upward, pressing the measure of clay t" against the rigid plate 7c', immediately above the cylinder. This gives the brick its form. As the crank moves on and turns downward it allows the ram, with the formed brick, to drop slightly away from the plate. As the cylinder is turned through its next one-fourth revolution the ram glides off the lever onto the elevator e', and, arriving at the top of thelatter, the brick Z is raised out of the mold. (See Figs. l, 3, and 4:.) y

The pressing-plate 7o is held by the central spindle b, Fig. 6, and by stout posts n. The brick being raised out of the mold is delivered upon a carrier, as a belt o', by an automatic discharger. This discharger, as shown, consists of a push-iin ger p to push the brick off the cylinder, operated by means of an eccentric fr', secured to the shaft t. The push-finger turns upon a bearing s over the cylinder, held by a standard t', secured to the spindle b. An arm u' extends downward and is connected with the eccentric by a conn ecting-bar o and eccentric-strap w. The throw of the eccentric, as indicated in Fig. l, causes the brick to be delivered to the carrier 0', which may be of any length wished and may lead to any desired point.

The carrier o for the brick is driven by means of a horizontal shaft d2, turned by a belt b2, running from the main driving-shaft (l, Figs. l and 4. T ie shaft dglis held in standards c2 and d2, the latter having a rigid stud e2, upon which the pulley f2 for the carrier o turns. A vertical belt g2, driven by the shaft a2, turns the pulleys h2 and f 2 on the stud e2. At the other end the carrier o is su pported by a simple standard 2.

The feed-pan C has an opening 7a2 formed through the bottom, under which a mold-cavity c stands when the wheel stops after each motion given it by the segmental gear u.

The elevator-incline e drops rapidlyaway after reaching its highest point, as shown in Fig. 2, so that when a mold-cavity has reached the opening 7a2 the ram will have dropped downward from gravity, leaving a large space above its upper end, as shown in Figs. 5, 6, and 7. Into this space the clay in the feedpan is swept by the feeders D. The clay,

The,

which is in a semi-duid state, flows from the hopper into the pan through an opening Z2, the size of the opening being regulated by a vertical sliding door n2, operated by a handlever 02.

To prevent the rams dropping out of their places, I provide each with simple stops p2, Figs. 6 and 7, rigid in the mold-cylinder E. The. rams are each formed with -longitudinal grooves #"5 in their opposite edges, in which to receive the ends of the stops. The grooves terminate at such points that lthe rams are prevented from'descending too far or drop- VVping out of their respective cavities. the crank turns up against the latter, driving The form of the feeder D is not essential, its only function being to sweep the fluid clay down into the respective molds as they are presented to the opening in the feed-pan. As shown, it is formed with sectoral parts or wings s2, reaching out from a hub, the sectoral parts having downturned edges or scrapers t2, extending to the bottom of the pan.

The clay may be supplied to the hopper by any convenient means, as by a'spout or chute.

The operation of the machine is briefly as follows: The clay being supplied to t-he hopper is therein thoroughly cut and mixed by the revolving partsB and iiows into the feedpan C. The mold-cylinder always stops with a mold directly under the opening in the pan, and while stationary the revolving feeder D scrapes the clay down into the mold in a quantity sufficient to form a brick. At the next quarter-turn of the mold-cylinder another mold is brought beneath the opening in the feed-pan, and the mold just filled is simul- Ytaneously carried to a point over thedriver for the ram. While the mold-cylinder is again motionless the driving-crank turns upward -and drives the ram toward the rigid pressing-plate k', giving to the mass of clay in the mold a true prismatic form with sharp corners and edges. Two more movements of the mold-cylinder cause the ram to raise the brick out of the mold and present it to the discharger, by which it is discharged onto the carrier o', as before described. Each complete'revolution of the mold-cylinder, when constructed as shown, turns out four bricks. Of course the size of t-he cylinder and number of molds formed therein may be changed as may be desired, or the parts may be duplicated in the machine, so as to increase the rate at which it will form the bricks, without departing from the spirit of our invention.

This machine is also adapted to make tile or hollow work by changing the form of the molds and rams. It is also adapted to press blocks of papier-mache or similar substances.
